-== DESCRIPTION
-
-IMPORTANT: These functions are deprecated.  Please see xref:nng_socket_get.3.adoc[nng_socket_get].
-They may not be present if the library was built with `NNG_ELIDE_DEPRECATED`.
-
-(((options, socket)))
-The `nng_getopt()` functions are used to retrieve option values for
-the xref:nng_socket.5.adoc[socket] _s_.
-The actual options that may be retrieved in this way vary.
-A number of them are documented in xref:nng_options.5.adoc[nng_options(5)].
-
-Additionally transport-specific options and protocol-specific options are
-documented with the transports and protocols themselves.
-
-=== Forms
-
-In all of these forms, the option _opt_ is retrieved from the socket _s_.
-The forms vary based on the type of the option they take.
-
-The details of the type, size, and semantics of the option will depend
-on the actual option, and will be documented with the option itself.
-
-`nng_getopt()`::
-This function is untyped and can be used to retrieve the value of any option.
-The caller must store a pointer to a buffer to receive the value in _val_,
-and the size of the buffer shall be stored at the location referenced by
-_valszp_.
-+
-When the function returns, the actual size of the data copied (or that
-would have been copied if sufficient space were present) is stored at
-the location referenced by _valszp_.
-If the caller's buffer is not large enough to hold the entire object,
-then the copy is truncated.
-Therefore the caller should check for truncation by verifying that the
-returned size in _valszp_ does not exceed the original buffer size.
-+
-It is acceptable to pass `NULL` for _val_ if the value in _valszp_ is zero.
-This can be used to determine the size of the buffer needed to receive
-the object.
-+
-TIP: It may be easier to use one of the typed forms of this function.
-
-`nng_getopt_bool()`::
-This function is for options which take a Boolean (`bool`).
-The value will be stored at _bvalp_.
-
-`nng_getopt_int()`::
-This function is for options which take an integer (`int`).
-The value will be stored at _ivalp_.
-
-`nng_getopt_ms()`::
-This function is used to retrieve time xref:nng_duration.5.adoc[durations]
-(such as timeouts), stored in _durp_ as a number of milliseconds.
-(The special value ((`NNG_DURATION_INFINITE`)) means an infinite amount of time, and
-the special value ((`NNG_DURATION_DEFAULT`)) means a context-specific default.)
-
-`nng_getopt_ptr()`::
-This function is used to retrieve a pointer, _ptr_, to structured data.
-The data referenced by _ptr_ is generally managed using other functions.
-Note that this form is somewhat special in that the object is generally
-not copied, but instead the *pointer* to the object is copied.
-
-`nng_getopt_size()`::
-This function is used to retrieve a size into the pointer _zp_,
-typically for buffer sizes, message maximum sizes, and similar options.
-
-`nng_getopt_string()`::
-This function is used to retrieve a string into _strp_.
-This string is created from the source using xref:nng_strdup.3.adoc[`nng_strdup()`]
-and consequently must be freed by the caller using
-xref:nng_strfree.3.adoc[`nng_strfree()`] when it is no longer needed.
-
-`nng_getopt_uint64()`::
-This function is used to retrieve a 64-bit unsigned value into the value
-referenced by _u64p_.
-This is typically used for options related to identifiers, network
-numbers, and similar.
-
-== RETURN VALUES
-
-These functions return 0 on success, and non-zero otherwise.
-
-== ERRORS
-
-[horizontal]
-`NNG_EBADTYPE`:: Incorrect type for option.
-`NNG_ECLOSED`:: Parameter _s_ does not refer to an open socket.
-`NNG_EINVAL`:: Size of destination _val_ too small for object.
-`NNG_ENOMEM`:: Insufficient memory exists.
-`NNG_ENOTSUP`:: The option _opt_ is not supported.
-`NNG_EWRITEONLY`:: The option _opt_ is write-only.
